When it is desired to lock this lever in itsv neutral position, the `rod' 27 is rotated. by

means of its key barrel to the position shown in Fie. 1 so that the trunnions 18 are forced outward by means of the lower end of the rod 2.7 into the pockets 21 to prevent thering 15 from beingV rocked upon itstrunnions 16.

From the mechanism just described, it will be seen that my locking means operates to prevent the gear shift lever 10 from being rocked upon one pair of its supporting trunnions, thus 'limiting the rocking movelment of the lever to a .single vertical plane.

In the embodiment of my invention. illustrated, I have shown a' guide 28 mounted ywithin the lower portion of the supporting bracket 14, and this guide is provided with the notch 29 positioned to receive the lower end of the gear shift lever 11 when the same is in its neutral position. This guide 28 is positioned within its bracket to prevent the lever from being shifted in a forward or rearward direction until` it has first been moved slightlyin a lateral directioinand in the embodiment of my invention illustrated, I haveshown the sliding trunnions 18 positioned to prevent the lever 10 from being moved in a lateralv position sufficiently to disengage its lower end from thenotch Q9 after the trunnions 18 havebeen forced outward into locking engagement with the bracket 14s. als just stated, the sliding trunnions 18 are positioned to prevent the lever 10 from being rocked laterally when these trunnions are moved into engagement with the bracket l-l, but obviously, if desired, these trunnions might be positioned to lie in a plane at right angles to that illustrated in the drawings to thereby prevent the lever 10 from being rocked in a forward and rearward direction irrespective of the operation of the guide 28.

It will be apparent that various minor changes may be made in the device herein described without departing` from the scope of my invention as defined in the annexed claims.

What I claim is: 1. In combination with a gear shift lever, a bracket. swingingly supporting the same, supporting trunnions forsaid lever extending at right angles to each other, one pair lof trunnions movable axially, and key operable means for sliding said trunnions into locking engagement with said bracket to lock said lever.

In combination with a gear shift lever,

a supporting bracket, ti'unnions extending ingly mounted upon said bracket, trunnions for swingingly supporting (said lever upon said support, and key-controlled means for forcing said trunnions outward into locking engagement with said bracket to lock said lever against movement.

4. In coinbination'witli a gear shift lever, a supporting bracket, a supporting ring rockingly mounted upon said bracket, trunnions for swingingly mounting said lever within said ring, and key-controlled means forrigidly securing said ring to said bracket to thereby prevent the operation of said lever.

5.k In coinbinationwith an operating lever, a supporting bracket, a supporting,- ring rockingly mounted upon said bracket, trunnions for swingly mounting said lever within said ring, and key-controlled means for forcing said trunnions outwardly into locking engagement withA said bracket to render said lever inoperative.

6. In combination with an operating lever, a supporting bracket, trunnions extending at right angles to each other for swingingly supporting said lever upon said bracket, and key-controlled means movable into position to block the swing of said lever upon one pair. of its supporting trunnions.

7. In combination with a gear shift lever,

a supporting bracket, trunnions extending' at right angles to each other for swingingly supporting said lever within said bracket, onek pairV of trunnions slidably mounted within said lever, and key-controlled means rotatably mounted within said lever and constructed to force said sliding trunnions outward into locking engagement with said bracket to thereby lock said levery against movement.

8. In combination wit-h a gear shift lever, a supporting bracket, trunnions extending at right angles to each other for swingingly supportingsaid lever within said bracket, one pair of trunnions slidably mounted within. said lever, said bracket having relatively -shallow concave pockets formed therein and positioned to receive the ends of said sliding trunnions, and key-controlled means for forcing said trunnions outward into said pockets to lock said lever against movement.

9. In combination, an operating lever, a supporting bracket therefor, a lever support swingingly mounted upon said bracket, said operating lever being swingingly mounted upon said lever support, and key-controlled means mounted in the lever for locking said lever support against movement.

10. In combination, a supporting bracket, a swinging lever-support mounted thereon, an operating lever carried by said leversupport and key-controlled means engaging said lever support and lever to support the latter and movable into engagement with the bracket for locking said lever-support against move-ment.

11. In combination with an operating lever, a supporting bracket, pairs of trunnions mounting said operating lever thereon, one pair of said trunnions being movable into position 4to lock the lever against movement about the other pair and key-controlled means for moving said trunnions into said position.

12. In combination, a supporting bracket, a lever, means including a pair of trunnions to swingingly mount said lever on said bracket and key-controlledv means to move said trunnions into locking engagement with said bracket.

13. In combination, a supporting bracket, a lever support swingingly mounted thereon, an operating lever, a pair of trunnions mounting said lever on said support and movable into position to lock said support against movement.

14. In combination, a supporting bracket, a lever support swingingly mounted thereon, an operating lever, and common means for supporting said lever on said support and locking said support against movement.

15. In combination, a supporting bracket, a ring rockingly mounted thereon, a lever passing through said ring and pivotally carried thereby, and key controlled means for klocking said ring against movement rela.-

tively to the support.

16. In combination, a supporting bracket, a ring rockingly mounted thereon, a lever passing through said ring and pivotally car` ried thereby, and key controlled means mounted in the lever for locking said ring against movement relatively to the support.

In Witness whereof, I have hereunto set my hand on the 28th day of November, 1919.
